如何在swift中添加位置图标？

问题描述：

我该如何将这些东西添加到我的项目中。它们是否集成在MKMapView？如何在swift中添加位置图标？

我没有找到关于他们的互联网什么。

再见地图 – Ved

好创建的UIView，但我怎么能安装该系统的部位图标使用外部图像白化？（对不起，我的英语） –

有没有像屏幕右上角的“我”圈 –

上创建MKMapView的顶部的两个按钮添加则它们的约束在viewDidLayourSubviews功能编写此代码舍入所希望的角部和阴影和图像添加到按钮。从身份检查员中选择他们的浅灰色背景颜色。

override func viewDidLayoutSubviews() { 

let infoButtonShape = CAShapeLayer() 
infoButtonShape.bounds = infoButton.frame 
infoButtonShape.position = infoButton.center 

let locationButtonShape = CAShapeLayer() 
locationButtonShape.bounds = locationButton.frame 
locationButtonShape.position = locationButton.center 


infoButton.clipsToBounds = true 
infoButton.layer.masksToBounds = false 
infoButton.layer.shadowColor = UIColor.white.cgColor 
infoButton.layer.shadowRadius = 2 
infoButton.layer.shadowOpacity = 0.5 
infoButton.layer.shadowOffset = CGSize(width: 2, height: -2) 
infoButton.layer.shadowPath = UIBezierPath(rect: infoButton.bounds).cgPath 



locationButton.clipsToBounds = true 
locationButton.layer.masksToBounds = false 
locationButton.layer.shadowColor = UIColor.white.cgColor 
locationButton.layer.shadowRadius = 2 
locationButton.layer.shadowOpacity = 0.5 
locationButton.layer.shadowOffset = CGSize(width: -2, height: 2) 
locationButton.layer.shadowPath = UIBezierPath(rect: locationButton.bounds).cgPath 

infoButton.layer.shouldRasterize = true 
locationButton.layer.shouldRasterize = true 

locationButtonShape.path = UIBezierPath(roundedRect: locationButton.bounds, byRoundingCorners: [UIRectCorner.bottomLeft , UIRectCorner.bottomRight], cornerRadii: CGSize(width:10.0, height:10.0)).cgPath 

infoButtonShape.path = UIBezierPath(roundedRect: infoButton.bounds, byRoundingCorners: [UIRectCorner.topRight , UIRectCorner.topLeft], cornerRadii: CGSize(width:10.0, height:10.0)).cgPath 

infoButton.layer.mask = infoButtonShape 
locationButton.layer.mask = locationButtonShape 

infoButton.contentMode = .scaleAspectFit 
locationButton.contentMode = .scaleAspectFit 


infoButton.setImage(#imageLiteral(resourceName: "information-icon-3"), for: .normal) 
locationButton.setImage(#imageLiteral(resourceName: "LocationArrow-512"), for: .normal) 


}

然后添加按钮的IBAction更新位置

let manager = CLLocationManager() 

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 

//Use location.last add to map then stop updating location 
manager.stopUpdatingLocation() 

} 

@IBAction func updateLocationAction(_ sender: UIButton) { 

manager.startUpdatingLocation() 
}

对于两个其它UIViews只是创建一个UILabel用于温度以及用于云图标一个的UIImageView。对于UILabel和UIImageView的背景颜色及其圆角半径，您可以做类似于我为按钮所做的操作，但是这次为UIImageView和UILabel的左角选择了正确的角点。

这里是输出：当然，您可以使用更好的大小的图标图像为您的按钮。

很棒，谢谢。明天我会试试它！ –
